Tens of protestors organized Monday a demonstration against Egyptian-Saudi agreement on two Red Sea islands of Tiran and Sanafir, in front of syndicate of engineers at Ramsis street, downtown Cairo, Al Bawaba News reported. The demonstration was initially set to be held in front of syndicate of journalists, but several individuals had organized a pro-government demonstration there. Protestors who refuse the Egyptian-Saudi agreement on the two islands have opted to hold the demonstration in front of syndicate of engineers in order not to clash with pro-government supporters. Muslim Brotherhood (MB) terrorist group and several political movements, such as 6th of April and Revolutionary Socialists movements had called for a demonstration against the Egyptian-Saudi agreement on the two islands on April 25, which marks the Sinai Liberation Day.
